    Only 2 and - 5 are roots. Any other number is not a root.

    Step-by-step explanation:

    The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.

    The f (x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into

    f (x) = (x - 2) (x-2) (x+5) (x-2) = 0.

    Set each factor equal to 0 and solve.

    x - 2 = 0 so x = 2. This repeats twice.

    x + 5 = 0 so x = - 5.

    So the zeros are 2, - 5.
